The paper presents an analysis of the Akagi’s p-q theory and its implementation for active filtering under nonsinusoidal voltage conditions. A modified definition of the active component of the current for such conditions is proposed. Next, our platform for testing control strategies of parallel shunt filters, based on a DSP DS1103 system, is presented. An implementation of the modified p-q theory on the dSpace 1103 DSP system and some experimental results are presented in the second part of the paper.

Artykuł przedstawia analizę teorii mocy p-q Akagi’ego i jej zastosowań do aktywnej filtracji w warunkach niesinusoidalnych. Proponowana jest też, zmodyfikowana dla takich warunków, definicja składowej czynnej prądu. Artykuł omawia następnie zestaw laboratoryjny do testowania strategii sterowania równoległego filtru aktywnego, oparty na systemie DS1103 cyfrowej obróbki sygnałów (DSP). W części drugiej przedstawiono zastosowanie zmodifikowanej teorii p-q do sterowania filtru aktywnego z użyciem systemu DSP dSpace 1103 oraz otrzymane wyniki eksperymentalne.
